i just tested launching jenesis(0.6) from the main eos menu via HBmenu.
i tried altered beast, another world, and boogerman...they all worked/played fine for me.

i only tried it from EOS, so i dunno bout launching HBmenu from iMenu, or from the Plugin menu.

edit: wowzers im out of date on the jenesis...i looked it up on filetrip and 0.74 is the newest,
and it does indeed freeze for me as well when trying to play a game.
so i guess its good news that you could use the older 0.6 version if you want to run it through HBmenu =)

n/p, glad to oblige =)
a big part of the fun with DS for me is tinkering around with the apps =D
i originally put the HBmenu on my card because BAGs 'Etch' drawing app needs its nitrofs to run on dstwo
